“…The effects of supplementing sheep with spineless cactus, as well as in performance evaluation, were observed under meat quality. For instance, it improved lipid profile ( 113 , 114 ) and meat sensory quality ( 117 ). In addition, this cactus could replace maniçoba ( M. pseudogalziovii Pax and Hoffman) hay by up to 33% with increased carcass finishing fat without compromising meat quality ( 115 ).…”

Technologies Used in Production Systems for Santa Inês Sheep: A Systematic Review

2022

View full text Add to dashboard Cite

This study identifies the number of publications that presented technologies used in the production systems of Santa Inês sheep in the last 5 years (2017–2021) carried out in Brazil. Therefore, the objective was to identify where we are in terms of knowledge about technologies in different fields (health, reproduction, animal breeding, behavior and welfare, nutrition and feeding, forage and pasture, carcass and meat quality, and economics and management of livestock systems). After rigorous selection, 114 studies were appointed and classified by knowledge field, and the main approaches within each theme were evaluated, pointing out research gaps. Most technologies have been in northeastern states. However, government agencies should develop public policies to disseminate techniques in rural areas because the production system in this region is still subsistence. This study highlighted the need for works that present management practices and tools that impact the improvement of animal welfare. Agro-industrial by-products have been widely used as an alternative for sheep feeding. However, economic feasibility analyses are recommended with these foodstuffs to substantiate their use as an option to reduce production costs. There is a lack of research allusive to the management of production systems, especially those related to estimates of economic feasibility indicators.

This meta-analysis summarizes the effects of incorporating sugarcane or its by-products into the diet of sheep from various aspects including productivity, carcass characteristics, meat quality of the longissimus muscle, and milk quality. Study differences were defined as random factors while fixed factors accounted for the levels of sugarcane supplementation in the sheep diet. The analysis also examined differences in categorical factors such as sugarcane form (whole, top leaves, bagasse, and residue) and pretreatment methods (untreated, hydrolyzed, and ensiled). Adding sugarcane to the sheep diet showed a significant increase in average daily weight gain (ADG) and feed conversion ratio (FCR) (P < 0.05). However, there was a significant decrease in hot carcass weight (HCW), cold carcass weight (CCW), and dressing percentage (DP) (P < 0.05). Color variables, such as redness (a*) and brightness (L*), of sheep meat were higher when fed a sugarcane-based diet provided in the form of whole plant (P< 0.05). Moreover, there was a significant decrease in lactose and protein concentrations in sheep milk (P < 0.05) after feeding a sugarcane-based diet. Overall, sugarcane supplementation showed some benefits in sheep productivity variables, but it did not yield the expected results in maintaining carcass characteristics, longissimus muscle, and milk quality.

Correlation between mineral profile, physical-chemical characteristics, and proximate composition of meat from Santa Ines ewes under water restriction

et al. 2023

View full text Add to dashboard Cite

This study aimed to evaluate the correlations between mineral profile, physical and chemical characteristics, and proximate composition of ewe meat receiving different water supply levels (100% - ad libitum group; 80%; 60% and 40% ad libitum group). Thirty-two Santa Ines ewes were assigned to a randomized block design, with 4 treatments, and 8 replications, during the 63-day experimental period. Significant correlations between all minerals (P<0.05) were found in the 60% and 40% water supply levels. A correlation (P<0.05) was observed for minerals P, K, Ca, Mg, S, Cu, and Fe with crude protein at 100% water supply. Negative correlations (P<0.05) between N, P, K, Ca, Mg, S, Cu, Fe, and Zn were detected in the meat of animals supplied with 60% water. Principal component analysis (PCA) of macrominerals explained 82.9% data variance. Zinc had a strong contribution to PC1. Cooking losses had a similar contribution to PC1 and PC2. PC1 and PC2 explained 66.7% data variance in chemical characteristics. The decrease in water supply causes the correlation of nitrogen with the other minerals in meat, in addition to altering the correlation between the physical and chemical profile of the meat.
